MEANS FOR SUPPORTING LEVERIS IN TRACK-SCALES.

Application filed December 6, 1909.

To all whom it may concern:

Be it known that I, PERLEY F. HAZEN, a citizen of the United States, residing at St. Johnsbury, in the county of Caledonia, State of Vermont, have invented certain new and useful Improvements in Means for Supporting Levers in Track-Scales, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

My invention relates to an improvement in railway track scales. In such scales, it has been customary to anchor down rigidly to the pit timbers, the even lever or even balancing beam, as well as the fifth lever which runs transversely of the even lever; the purpose of the even lever being to transmit the swinging movement of certain of the longitudinal levers to other longitudinal levers to be in proper direction for the movement of the fifth lever. It has also been the practice to hang these levers from their supporting longitudinal levers, by means of turn buckles. In the first instance, leveling up of the levers separately as the scale is installed is not permitted, and in the second instance only a comparatively limited range of adjustment is permitted, unless the turn buckles'are made so long as to make it necessary to deepen the pit. V

The object of the present invention is to provide a novel form of connection between the longitudinal levers and the even lever and fifth lever, whereby saving in the, depth of the pit, greater range of adjustment, and economy of construction, may be secured.

With these objects in view, therefore, the invention consists in the matters hereinafter described and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a side view; and Fig. 2 a front view, of my new form of connection; Fig. 3 is a detail view of the spacing plate or washer; and Figs. l and 5 are side views of modifications.

In these drawings, referring first to Figs. 1, 2 and 3, A represents the closed loop Specification of Letters Patent.

Serial No. 531,586.

' which is hung from the knife edge pivot a,

on the longitudinal levers (not shown). -B represents a stirrup loop depending from the loop A, and having its ends threaded and passing through openings in the plate C, nuts I) fitting the threaded ends. The screw-threaded shank c of a closed loop D passes up through the central opening in the plate C, and a nut d is adjustable thereon. A stirrup loop E is hung from the loop'D, and supports the knife edges of the even lever, or the fifth lever. By adjusting the nuts I), b, or cl, or all of them, the levers may be properly leveled up; furthermore, quite a range of adjustment is permitted, without increasing the depth of the pit.

In Fi 4c, the loop A is hung from the bearing a, and from its lower end is hung the eye bolt F, screw-threaded on its lower end, and passing through the central opening in the plate G. Through the other openings pass the threaded ends of the loop B, arranged reversely to the'loop B. Adjustment is effected by the nuts (5' and b. A. stirrup loop E is hung from the loop B.

In Fig. 5, the loop A supports the eye bolt F, which passes through the central opening in the plate, and is headed at d. It does not have a thread and nut adjustment. The stirrup loop B is similarly adjustably secured in the same manner as loop B by nuts 6, both these nuts and nuts 5 being held in place by jam nuts 0.

Having thus described my invention, what I claim as new and desire to secure by Letters Fatent, is

1. As a new article of manufacture, an adjustable connection for scale levers, c0mprising a plate having central and side openings, a bolt provided with a threaded shank passing through the central opening of said plate, and a nut mounted on said shank, a loop having its two ends passing through the other openings in said plate with nuts upon the ends of the opposite side of the plate from the nut on the first bolt.

2. As a new article of manufacture, an adjustable connection for scale levers, comprising a plate having a series of openings, a bolt provided with a threaded shank extending through the central opening of said In testimony whereof I aifix my signature, plate, a nut mounted on said shank, a stirin presence of two Witnesses.

rup 100p arranged in said loop provided PERLEY F HAZEN with bearing eyes, a second stirrup having threadedends securedin the opening of said \Vitnesses:

plate by nuts,vand a closed looparrzinged' in F RED' G. BECK,

said stirrup provided with a bearing. D. DEAN PATTERSON.
